java stax get string of inner node

Question

I am using java stax XMLStreamReader to read an xml. I want to grab the whole string of certain inner nodes.

XML:

<example>
   <ignoreMe>
      <bla></bla>
   </ignoreMe>
   <getMe>
      <data></data>
   </getMe>
</example>

I just want to be able to get the whole internal getMe node in a String. IE:

   <getMe>
      <data></data>
   </getMe>

Here is what I have.. but I am stuck:

XMLStreamReader parser = factory.createXMLStreamReader(new FileReader(file)); 
for (int event = parser.next();  
event != XMLStreamConstants.END_DOCUMENT;
event = parser.next()) {

    switch (event) {
    case XMLStreamConstants.START_ELEMENT:
        if (parser.getLocalName().equals("GetMe")) {
             //??????????????????

I started learning StaX last week, but if you are still looking for an answer to your problem, this may help you :

    XMLInputFactory xmlif = XMLInputFactory.newInstance();
    xmlif.setProperty(XMLInputFactory.IS_COALESCING, true);
    XMLStreamReader xmlsr;
    String resultat="";
    boolean isGetme=false;

    try {
        xmlsr = xmlif.createXMLStreamReader(new FileReader("lib/toto.xml"));
        int eventType;
        while (xmlsr.hasNext()) {
            eventType = xmlsr.next();
            switch (eventType) {
                case XMLStreamConstants.START_ELEMENT:
                    if(xmlsr.getLocalName().equals("getMe")){
                        isGetme=true;
                    }
                    if(isGetme){
                        resultat+="<"+xmlsr.getLocalName()+">";
                    }
                    break;
                case XMLStreamConstants.CHARACTERS:
                    if(isGetme){
                        resultat+=xmlsr.getText();
                    }
                    break;
                case XMLStreamConstants.END_ELEMENT:
                    if(xmlsr.getLocalName().equals("getMe")){
                        resultat+="</"+xmlsr.getLocalName()+">";
                        isGetme=false;
                    }
                    if(isGetme && !xmlsr.getLocalName().equals("getMe")){
                        resultat+="</"+xmlsr.getLocalName()+">";
                    }
                    break;
                default:
                    break;
            }
        }
    } catch (FileNotFoundException e) {
        e.printStackTrace();
    } catch (XMLStreamException e) {
        e.printStackTrace();
    }
    System.out.println(resultat);

This code will get you all the inner nodes and text contents, and store it into a String. I.E:

<getMe>
      <data>test</data>
</getMe>

However, this code is quite "ugly" and is surely not the best solution for what you are looking for, JDOM may be more suited to your needs.
